K'NEX MSMC V.2 (Build)


Introduction: K'NEX MSMC V.2 (Build)

About: K'NEX gun builder here at Instructables. More or less retired from the community, but I still pop in now and again.

Lets revamp a classic, shall we? The INSAS MSMC, featured in Black Ops II, is one of the best SMGs in game, and now you have the opportunity to build it out of K'NEX. How awesome is that?


  • Great sights
  • Flip up front sight
  • Extendable stock
  • High capacity magazine: 10 - 16 rds.
  • Sturdy body
  • Exact in dimensions
  • Comfortable trigger
  • 6 in. + pin pull
  • Good / average range: 30 - 50 ft.
  • Sturdy magazine
  • New magazine with bullet containment system

Lets build it!

Step 1: The Left Panel

Pretty easy...

Step 2: The Internals

Again, pretty easy, if you have any questions, contact me.

Step 3: Right Panel + Extras and Rubber Bands

We really are almost done, go crazy.

Step 4: The Magazine

The brand new magazine containment system. Brilliant, if I do say so my self.

Step 5: The Stock and the End

And we are done, as always if you have any questions, let me know, I'm happy to help!

Thanks for building my MSMC V.2! You guys are the best! Don't forget to comment and favorite, and I'll TTYL!

Hey man i freaking love your stuff so realistic. I was wondering if you wanted to do a collaboration some time?

Thanks man, that is a huge complement! I'd love to do a collab some time, the only problem is that I don't have much time for K'NEX anymore...

Oh heck yeah! mmmmmmmm...... So good!
Such an awesome submachine gun! Good job! I'll be building this immediately after I finish and post my project I've been working on this week.
But yeah very awesome!

Been doing alright, crazy busy. School has kind of been suppressing my hobbies and even work. As I've always said "school comes first".

Other than that craziness, my internship has taught me some sweet new mechanisms a principles which I'm going to try to apply to my knex projects.

Yeah, pretty much sounds like my life, only more work and less school. Yeah, I don't have time for much now-a-days, but I get today and tomorrow off, so I'll be building K'NEX guns, playing video games, and trying to spend some time on social media. You know, LOL, the important stuff. ;)

Awesome dude! I've kinda dropped my idea of becoming a mechanical engineer, and I think I plan on becoming a gunsmith... We'll see where that goes...

That's pretty interesting! What do have to study to be a gunsmith? I assume a lot of machining related classes.

Well, you see, I'm not 100% sure. You can do internships, apprenticeships, take classes, go to colleges... There are all kinds of things you CAN do, what you SHOULD do is a different matter... I don't really know what I should do...

Well... knowing what I do know about making guns, if you were to go to college... I would have a major of a Machinist. There is a lot of high precision lathe and mill work involved in the gunsmith trade. Other than that aim at trying to intern because you would have to know somebody to get into there without experience.
